How pyjamas originated: A look into their history
What is the history of pyjamas? Pyjamas had an intriguing and international history. The term originated from the Hindi and Persian words 'pāy-jāma' or 'pāy-jāmeh', which imply "leg clothing." Originally, they referred to loose-fitting pants fastened at the waist.

Eventually, these nightgowns evolved into a matching top and bottom set, which was adopted by both men and women. Today, pyjamas are a global fashion category, firmly founded in comfort but dressed in myriad different forms.
